codeigniter 2 typehinting loading model IN PHPStorm 2016.3.3

Let's pretend I am stuck in a time capsule in 2012 and I am still working in codeigniter 2 how can I typehint a loaded model in my controller so my editor find the functions etc.

my model is named profilemodel.php

I currently do this in the controller constructor:

/** var profilemodel $profileModel */
$profileModel = $this->load->model('profilemodel');

And I do this in a method in the controller:

$profileModel->getUserByEmail($user);

But this doesn't seem to be working

Anyone has any idea how I can do this?
